Filter the list of tags and display only tags matching the entered text. Spaces are word separators. If no tags are matching the filter, WinCatalog suggests to add a new tag. Press [Enter] to add the tag.
The tags assigned with just some of the selected items are marked as gray. Marking the grayed tag will associate it with all the selected items. Unmarking the grayed tag will clear the association for all the selected items. Leaving the tag gray will leave the association unchanged.
If this option is not set, tags will be applied to the selected items only. If this option is set, tags will be applied to the selected items, and to all sub-folders and files recursively.
